ABSTRACT:
A nebulizer system for producing a humidified and heated breathing gas to be inhaled by a patient undergoing inhalation therapy. The nebulizer system includes a nebulizer module and a heater module affixed to one another and optionally detachably connected to each other. The nebulizer module is connectable to an oxygen source, a liquid water supply, and, through an outlet, to a breathing apparatus. A throat in the system serves to direct an aerosol spray produced in the nebulizer module to a heat transfer element in a conical flow pattern. The heat transfer element is disposed substantially normal to the flow path of the generated aerosol and is in a direct heat transfer relationship with an outer peripheral portion of the conical flow pattern exhausted from the throat. In this manner, a self-regulating heat input is provided by the present nebulizer system.
